Question

Please show you work so i can follow what you are doing.

A positively charged particle Q_1 = +35 nC is held fixed at the origin. A second charge Q_2 of mass m = 5.5 mug is floating a distance d = 25 cm above charge Q_1. The net force on Q_2 is equal to zero. Which of the following represents the free-body diagram of charge Q_2? What is the sign of the charge on Q_2? Write an equation for the magnitude of charge Q_2 in terms of the given variables. Calculate the magnitude of Q_2 in units of nanocoulombs.

Explanation / Answer

weight is balenced by repelling force

mg=(1/4Pi*epselon)*q1q2/d^2

d) solving the abov equation

5.5*10^-6*9.8 = (9*10^9)*(35nc*q2)/(0.25)^2

q2= 1.06x10^-17 nano columbs
